Why 55mm f/4.5 Apo-Grandagon *and* 55mm f/4.5 Grandagon-N?

Dan, is that not what I wrote? There is some kind of crazy going on here.

... and the misquote is not appreciated.

I didn't quote you at all. And you've forgotten what you wrote:

Two things - it is not sharp until ƒ/16 or ƒ22, and those are coincidentally the apertures required with Rodenstock's center filter.

Two stops down from f/4.5 is f/9.
